Basic introduction
Canon ultimate helper logo
Contains lens data for more than 130 Canon mounts, including lenses from Canon, Sigma, Tamron, Tokina, Zeiss, Samyang and Voigtlander. This data includes resolution, vignetting, distortion, chromatic aberration and lens specifications. You can view these data separately; you can also use this app to sort specific data and focus on the lenses you are interested in; you can also compare different lenses to see the differences between lenses at different focal lengths and apertures. It also provides multiple calculators commonly used in photography: depth of field and hyperfocal distance calculations, field of view calculations, angle of view calculations, magnification calculations and circle of confusion diameter calculations. The specific functions are as follows: 1. Lens analysis includes the resolution, vignetting, distortion, chromatic aberration and specifications of each lens. Data can be displayed according to aperture or focal length. Some lenses provide data on both full-frame and half-frame bodies. 2 Lens ranking focal lengths are divided into less than 20mm, 20-28mm, 35mm, 50mm, 85mm and greater than 135mm. Apertures are divided into less than f/2, f2.8, f/4, f5.6, f/8 and greater than f/8. Rank the lens for resolution, distortion, chromatic aberration and vignetting at these focal lengths and apertures. 3 Lens comparison Compare the resolution, distortion, chromatic aberration and vignetting of multiple lenses at will. Generate multiple tables according to different focal lengths. Data for different apertures at that focal length are shown in each table. 4 Depth of field and hyperfocal distance calculation Calculate the depth of field and hyperfocal distance based on the input focal length, object distance, body and other conditions, and display them in tables and schematics respectively. 5 Field of view and angle of view calculation Calculate the field of view and angle of view based on the input focal length and body. 6 Bokeh and Circle of Confusion Diameter Calculation Calculate the diameter of the circle of confusion at a certain distance from the photographed object. Provides a reference for the lens’s blurring capabilities at different apertures and focal lengths.
